Postcard Sunday: Alps (More countries)

Prehistoric pile dwellings around the Alps is a series of prehistoric pile-dwelling (or stilt house) settlements in and around the Alps built from around 5000 to 500 B.C. on the edges of lakes, rivers or wetlands. 111 sites, located in Austria (5 sites), France (11), Germany (18), Italy (19), Slovenia (2), and Switzerland (56), were added to UNESCO World Heritage Site list in 2011. In Slovenia, this is the first cultural world heritage site.

Excavations, only conducted in some of the sites, have yielded evidence that provides insight into life in prehistoric times during the Neolithic and Bronze Age in Alpine Europe and the way communities interacted with their environment. As the nomination stated, the settlements are a unique group of exceptionally well-preserved and culturally rich archaeological sites, which constitute one of the most important sources for the study of early agrarian societies in the region.

Contrary to popular belief, the houses were not erected over water, but on nearby marshy land. They were set on piles to protect against occasional flooding. Because the lakes have grown in size over time, many of the original piles are now under water, giving modern observers the false impression that they always had been.
